Traffic broken down by client for a graph over a time window, as compact CSV. Columns: start timestamp, end exclusive timestamp, client name, client version, operation name, request count, request latency p50 ms, request latency p99 ms, request with error count. Answers which clients call a graph, which client versions are still on the wire, and which client drives errors or latency. Clients that do not report apollographql-client-name/-version come back with empty name and version columns. Ranked by orderBy descending: default REQUEST_COUNT (busiest); REQUEST_WITH_ERROR_COUNT for most error-prone, REQUEST_LATENCY_P99_MS for slowest. variantName and operationName scope to one or more variants or operations by exact name (omit for all). Rows are one per client + version + operation, so a busy graph has far more groups than the other metrics tools: scope by operationName or raise limit when a breakdown looks truncated. Keep the default resolution of ENTIRE_RANGE for totals and top-N, which gives one row per group ranked over the whole window. DAY/HOUR/MINUTE give one row per group per bucket ranked within each bucket, so a window total then needs a per-group sum plus a limit big enough to cover every bucket; too small a limit silently undercounts. Only HOUR and MINUTE accept a to of now, so use them for bursts in the last 24 hours. Avoid MONTH: it labels buckets by calendar month, not by the requested window.
